Phage lambda must first attach to the host cell surface and insert bacteriophage DNA by contracting the sheath proteins. Upon entering the host cell, the linear double-stranded phage DNA is circularized to prepare for capsid protein synthesis. Next, the phage replicates the DNA genome and packages the DNA into capsids. Finally, the phage lyses the host cell and progeny phagesare released.A. occurs at random leading to the prevention of some key steps in the viral replication cycle.B. allows host cells to remember infection by copying small sections of viral DNA into RNA.C. destroys the infected cells and halts viral production.D. recognizes viral mRNA and prevents further viral gene expression.

Lytic cycle: In this cycle bacteriophage attach to the cell surface of bacteria, then inject double stranded genome into host, DNA replicates and synthesis of protein occurs, then capsid proteins make the capsid and DNA enters into int and finally when there is increased the number of phages or bulk of phages overfilled into the cell they will lyse the cell and released from the cells and find the other host cells to infect. So, when they destroys the infected cells then their viral production halts till find the new host cell.
Lysogenic cycle: In lysogenic cycle the bacteriophage attach with the cell membrane of the host cell and enter their DNA into the cytoplasm of cell but instead of replication of their DNA and synthesis of proteins they will integrate into the host genome and only replicate their when the host cell replicates. So, in this cycle is bacteriophage is remain inactive.

Answer: Option C.

Destroy the infected cells and halt viral production

Explanation:

Bacteriophage is a type of virus that infect bacteria and reproduce inside it. There are 6 stages of attack of bacteriophage it is called lytic cycle.

The lyticc cycle refers to the reproductive stages of bacteriophage, it result in the destruction of infected cell

Bacteriophage first attach to the host, then its penetrate inside the host, transcription, biosythesis(the DNA are replicated), maturation (the replicated DNA assembles) and lysis, the newly formed phages are released from the infected cell.
